A self-leveling system for a multi-purpose vehicle used primarily for off the road operations such as roadside mowing. The vehicle frame and operator's station will automatically remain substantially level on sidehills, and if a slope greater than a predetermined amount is encountered, the operator will be given a warning signal which, if ignored, will result in the shut-down of the vehicle's operating system and the vehicle will stop. If the operator chooses, the vehicle can be operated from a remote location after the warning signal is received.
